Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the battery if working on electrical components.

2. Remove Wheel

Tools Required: Jack and jack stands, lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel by loosening the lug nuts in a star pattern.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove the caliper by unscrewing the caliper bolts.
- Check the brake pads for uneven wear; replace if necessary.
Inspect and Resurface/Replace Rotors:
- Remove the rotor from the hub.
- Use a run-out gauge to check for warping; resurface if within spec or replace if excessively warped.
Reassemble Components:
- Replace the rotor (if necessary) and install the caliper with new brake pads.
- Torque caliper bolts to manufacturer's specifications (usually between 25-35 ft-lbs).

4. Inspect Suspension Components

Check control arms, bushings, and ball joints for any signs of wear.
Replace any damaged components to restore proper alignment and handling.

5. Reinstall Wheel and Final Checks

Tools Required: Torque wrench.
Reinstall the wheel and torque lug nuts to the manufacturer's specifications (typically 76-83 ft-lbs for RAV4).
Lower the vehicle back to the ground.
